Abstract: BACKGROUND Circadian rhythms are physical and behavioral changes that follow the 24-h cycle of Earth's light and temperature and are regulated by clock genes. Timeless (Tim) has been identified as a canonical clock gene in… read more here.

DOI: 10.1038/s41598-018-35626-7
Abstract: The effects of some abiotic (maternal photoperiod and offspring developmental temperature) and biotic (host quality during both maternal and offspring generations) factors on diapause induction were investigated for two sympatric strains of Trichogramma brassicae Bezdenko… read more here.

The Effects of Photoperiod on Diapause Induction in Hypena opulenta (Lepidoptera: Erebidae), a Biological Control Agent Against Invasive Swallow-Worts in North America

DOI: 10.1093/ee/nvaa030
Abstract: Abstract Many insects exhibit a short-day diapause response, whereby diapause is induced when daylength falls below a critical threshold. This response is an adaptation to ensure synchrony between periods of insect activity, and the availability… read more here.

DOI: 10.1111/1744-7917.12423
Abstract: A key adaptation in insects for dealing with variable environmental conditions is the ability to diapause. The tiger swallowtail butterflies, Papilio glaucus and P. canadensis are ideal species to explore the genetic causes and population… read more here.

DOI: 10.1111/imb.12332
Abstract: Diapause is a programmed dormancy that allows organisms to tolerate predictable periods of unfavourable conditions by temporarily halting development and reducing metabolism. Diapause is widespread amongst insects and is crucial for allowing organisms to coordinate… read more here.
